title: Higher risk of preeclampsia in the polycystic ovary syndrome. A case control study.
abstract: OBJECTIVE
  To determine whether the risk of pregnancy-induced hypertensive disorders (PIHD) is higher in patients with the polycystic ovary syndrome (PCOS) than in non-PCOS controls, matched for age and parity.
  
  
  METHODS
  Retrospective analysis of eighty-one patients with PCOS, consecutively becoming pregnant during a seven-year period. Each PCOS-patient was matched for age and parity with one control patient. Chi-squared, Mann-Whitney or Fisher's exact-tests were used for statistical analysis.
  
  
  RESULTS
  Overall incidence of PIHD was similar in both study groups. However, incidence of preeclampsia was significantly higher in patients with PCOS than in controls (P = 0.02). This higher incidence can not be explained by body mass index, endocrine profile before pregnancy, induction of ovulation or treatment regimens.
  
  
  CONCLUSIONS
  PCOS-patients are at a significantly higher risk for preeclampsia than non-PCOS controls.
